The Roman Catholic Church is one big line of tradition. A break from tradition is wrong. We are an inherently conservative institution, holding on to what our holy forefathers passed down to us. Singing and belting out tunes is not the height of active participation; actually, I’d call it a perfidious distraction to real prayer. Hymns like “Gather us in” are so sappy it’s a choke-hold on the faithful, putting them in the frame of a concert, or theater green room gathering for coffee, rather than being in the presence of mysterious and holy God.
Gregorian chant is hard for most to understand, but the ephemeral floating quality of the single melismatic line always shakes people to the core. Traditionalists don’t like Gregorian chant because it’s old, but because it’s a connection with so many of the saints. We feel as if we’re one in worship with all the past, hearing the same simple, angelic chant without need for instruments or tolerant, gushy, happy feelings. Gregorian chant was never considered “different” by the world. Ambrosian chant preceded it, Byzantine chant preceded that, and ancient Jewish and Roman chant preceded Byzantine. It is a very ancient tradition to sing to our God without need for instruments, but with a mysterious voice of ineffable joy.
If traditionalists got “hold” of the Church again, I dare say all the people who rely on happy-clappy hymns, guitar masses, and nonsense music would leave. If they were there only for the sense of “community” and not a sense of the terrible righteousness and awe of almighty God, they probably didn’t fit anyway. We need to evangelise all people, and we ourselves need to be evanglised… teary-eyed modernist music doesn’t put depth into anything or anyone. Neither does Gregorian chant, inherently, but it moves the soul to a non-harmonic world where only the One Voice of the saints and angels combines. It’s 100% different from hymns influenced by chorales and popular songs.
